Someone installed Google Analytics 4 on your website, gave you access, and now you log in once in a while, look at a chart of users going up and down, and close the tab. The left-hand menu has dozens of options, the labels change every so often, and it is hard to know which screens matter for a business your size.
This is GA4 reports explained for an owner, not an analyst. You need about five screens, each answering one practical question. The rest can wait until you have a specific reason to open it.
How GA4 is organised, in one minute
GA4 records events. A page loading is an event, a scroll is an event, a form being sent can be an event. Each event belongs to a session (one visit) and a user (one browser or device, as far as GA4 can tell). The events you care most about are marked as key events.
The standard reports sit under Reports in the left menu, grouped into collections. Many properties show a life-cycle grouping with acquisition, engagement and monetisation, but the arrangement can be customised and Google changes it now and then, so look for the report names rather than an exact path.
Two controls apply to almost every report: the date range at the top right, and comparisons, which let you set one group of visitors beside another. Learn those two and every report becomes more useful.
Realtime: is tracking working right now?
The Realtime report shows activity from the last few minutes. It is not a place to judge marketing. It is the quickest way to confirm the setup works.
Open your site on your phone, submit a test enquiry, and watch Realtime. Your visit should appear, and the event you use for enquiries should show in the event list. If it does not, there is no point reading the other reports until that is fixed.
Realtime is also handy on the day you launch a campaign or send a newsletter. You can see whether people are arriving from it before the standard reports catch up, since those take time to process.
Traffic acquisition: which channels bring visits
This report lists sessions by channel: organic search, paid search, organic social, email, referral, direct and so on. It answers “where did this month’s visits come from?”
The column worth adding to your mental checklist is key events. Sessions tell you volume. Key events by channel tell you which channels bring people who actually got in touch. A channel with fewer sessions but more enquiries is doing better than it looks on the first chart.
There is a sister report called User acquisition, which credits each user to the channel that first brought them. Traffic acquisition looks at each visit separately. For a monthly review, traffic acquisition is usually the more intuitive of the two. If your channel figures look odd, with lots of direct or unassigned traffic, our post on reading GA4 traffic sources explains the usual causes.
Pages and landing pages: which content works
Two reports under engagement deserve a regular look.
Pages and screens
This lists every page by views and engagement. It answers “what do people read on my site?” Use it to spot service pages nobody visits, or a blog post that is quietly attracting more readers than your home page.
Landing page
This lists the first page of each session. It is more useful for marketing, because it shows where people arrive from search, ads and links. Add key events to the view in your head: a landing page with plenty of sessions and no enquiries is a page worth rewriting or a campaign pointing at the wrong place.
Engagement rate appears in both. GA4 counts a session as engaged if it lasted beyond a short threshold, viewed more than one page, or included a key event. A low rate on a landing page suggests people are not finding what the ad or search result promised.
Events and key events: are people doing what matters?
The Events report lists everything GA4 recorded, with counts. Much of it is automatic: page_view, session_start, scroll, click. Your own events, such as an enquiry or a WhatsApp tap, appear here once they fire.
The key events report narrows the list to the actions you marked as important. This is the closest thing GA4 has to a results page. Read it for three things:
- Totals against your own records. If GA4 says twelve enquiries and you received five emails, something is double counting.
- Sudden drops to zero. Usually a form plugin change or a broken tag, not a sudden lack of interest.
- Odd new entries. An event someone marked as key without telling you, such as a scroll, will inflate the results.
How events become key events, and which ones to choose, is covered in our GA4 conversion tracking guide.
Comparisons: the feature that answers most questions
Most owner questions are comparisons. Did last month beat the month before? Do mobile visitors enquire as often as desktop ones? Did the new Google Ads campaign bring better visitors than Meta?
GA4 handles these two ways:
- Date comparison. In the date picker, switch on compare and choose the previous period or the same period last year. Seasonal businesses should prefer last year, since comparing a festival month with a quiet one says little.
- Comparisons by dimension. Add a comparison for, say, device category equals mobile, and another for desktop. Every chart in the report then splits into those groups.
Keep comparisons to two or three at once. More than that turns each chart into a tangle of lines.
GA4 reports you can safely ignore at first
GA4 offers a lot more than the screens above. Most small businesses can leave these alone until a specific question comes up:
| Area | What it is for | When it becomes useful |
|---|---|---|
| Explore | Custom tables, funnels and paths built by hand | When a standard report cannot answer a question you keep asking |
| Demographics and tech | Visitor country, city, language, browser, device | When you serve several regions or suspect a device-specific problem |
| Retention | How often users come back | For content sites and shops with repeat buyers |
| Monetisation | Purchases, revenue, items | Only once ecommerce events are set up on a shop |
| Advertising | Attribution models and conversion paths | When you run several paid channels and want to see how they overlap |
If Search Console is linked to the property, a search section can also appear showing queries next to landing pages. If you have not connected it yet, our post on linking WordPress to Search Console is the first step.
A short reading order for your monthly look
When you sit down to review, go in this order and the whole look stays short:
- Realtime, with a test enquiry, to make sure tracking still works.
- Key events for the month, compared with the previous period, checked against your inbox.
- Traffic acquisition with key events, to see which channels produced results.
- Landing page, to find pages that get visitors but no enquiries.
- One comparison that answers whatever question is on your mind this month.
Write down what you found and one thing you will change. For how this fits into wider measurement across ads, search and your own records, see our guide to marketing analytics for small businesses.
Frequently asked questions
Why do GA4 numbers change when I look at the same dates again later?
Standard reports take time to process, so recent days can fill in after you first look. Data thresholds and modelling can also adjust figures, especially when consent mode is active. For a monthly review, wait until the month has closed for a few days before writing down the numbers.
What is the difference between users and sessions in GA4?
A session is one visit. A user is the browser or device GA4 recognises, which may make several visits. One person on a phone and a laptop can appear as two users. For judging marketing, sessions and key events are usually more practical than user counts.
Can I hide reports I never use from the GA4 menu?
Yes. Property editors can customise the report collections in the library area of Reports, removing or adding reports and topics. Keep a copy of the default arrangement in mind, because other people with access may expect to find the standard screens.
Should I look at GA4 every day?
Not for decisions. Daily numbers for a small business swing too much to mean anything. A quick realtime check after a website change or campaign launch is sensible, but the useful review happens monthly, with a comparison against the previous period.
GA4 becomes much less confusing once the right events exist and the reports only show what matters to you. If yours is full of noise, or you are not sure the key events are counting real enquiries, our tracking setup service starts by checking what is already there. It is one part of our wider online marketing services.
